Rotor Retention and Loss Reduction for High-Speed Permanent Magnet Motor Generators

August 15, 2017

Electromechanical systems with permanent magnet rotors can operate as motors to convert electrical power into mechanical movement or as generators to convert mechanical movement into electrical power. High speed motors/generators are commonly used in different systems such as expanders in Organic Rankine Cycle waste heat recovery systems, flywheel-based energy storage systems, and electric turbo-charging and supercharging systems for marine engines and high performance vehicles. Design details of these systems are beyond the scope of this paper. The focus will be placed on the high-speed rotor which is a critical part of many integrated motor generator systems.
